FURNACE-FLUE CLEANER.

Specification of Letters Patent.

Patented Aug. 12, 1919.

Application filed April 17, 1919. Serial No. 290,767.

loit, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Furnace-Flue Cleaners, of which the following is a specification.

The present invention comprehends generally improvements in stoves and furnaces and more particularly relates to a flue cleaner.

It is the primary aim and object of this invention to provide a device'of the above mentioned character designed so that it can be easily inserted in a partly folded position into a furnace flue without scraping or pushing the dirt to the inner end of the flue and in addition is capable of being easily adjusted to assume an operative position so that when it is withdrawn the dirt, etc., will be scraped or removed from the flue.

More particularly this invention contemplates the provision of a device of the above mentioned character embodying a plate-like body with which is associated relatively adjustable operating handles so arranged that when moved relative to each other, that is, longitudinally, the plate-like body will be moved to an acute angle to the longitudinal axes of the main portion of the hanwith the accompanying drawings dles to permit of a quick easy insertion of the device in a flue and upon a reverse movement of the handles the plate-like body will assume a position in a plane at right angles to the axes of the handles or rods to insure the removal of dirt as the device is being withdrawn.

Among the other aims and objects of this invention may be recited the provision of a device of the above mentioned character with a view to compactness and wherein the number of parts are comparatively few, the construction simple, the cost of production low and the efliciency high.

Other objects, as well as the nature, characteristic features and scope of this invention will be more readily apparent fromthe following description taken in connection pointed out in the claims, forming a part of this specification. I

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a perspective view showing and the parts arranged in an operative position within a flue, the latter being broken away and shown in section.

Fig. 2 is a side elevational view of the same, with the parts occupying the position assumed at the time the device is being inserted, and A Fig. 3 is a transverse sectional view looking toward the inner face of the plate-like body.

Similar characters of reference are employed in all of the above described views, to lndicate corresponding parts.

Referring now, more particularly, to the accompanying drawings there is provided a plate-like body 1 formed of any suitable metal desirably-of a shape to conform to the contour of the inner surface of a flue 2, in the present instance being circular. Secured diametrically to one face of the body as by rivets 3 is a bracket 4 formed preferably of strap metal provided with spaced transversely arranged bearings 5.

As stated improved means are employed for manipulating the plate-like body and for adjusting it preparatory to and when it is arranged in the flue. In reducing this feature of the invention to practice-a pair of actuating members 6 and 7 are employed and are desirably formed from single pieces of relatively stiff wire or li ht rod metal. Brackets 8 in the form of oops are embraced about the main juxtaposed portions of the actuators 6 and 7, being carried at uniformly spaced intervals with the member 6 so as to serve as a means for guiding the relative sliding movement of the members. The inner portions 9 of these members are the actuators 6 and 7 are slid relative to each other the plate-like body will be moved so as to occupy a position in a plane at acute angles to the longitudinal axes of the main portions. Gripping handles 12 are formed on the opposite terminals of the actuators 6 and 7 and are designed for facilitating the relative sliding movement of the members for the arranging of the platelike body in the position shown in Fig. 2 so that it may be easily inserted in the flue,

and are capable of being alined with each that the advantages of the invention will be readily apparent.

Still further embodiments of the invention and those herein especially defined may be resorted to as conditions or preference may dictate, as may be in keeping with the hereto appended claims.

Having thus fully described the invention, What is claimed as new and desired to be secured by Letters Patent, is

l. A device of the character described including a plate-like body, a bracket secured to one face thereof and formed W1th face bearings, a pair of actuating members slidably connected to each other and having the inner terminals designed to form journaling portions for rockabl'e engagement in the bearings, and handles on the opposite terminals of the members designed for sliding the members relative to each other to adjust the plate-like body in different planes with respect to the longitudinal axes of the members and to also facihtate the manipulation of the device in its entirety.

2. A device of the character described including a plate-like body, a bracket secured to one face thereof and formed with face bearings, a pair of co-acting actuating members, means carried by one of the members in embracing the other member for.

slidably connecting the members together, the inner portions of the members being arranged in divergent relation withrespect to each other, triangular loops formed on the inner terminals of the members, the outer portions of which provide journals for rockable engagement with the bearings, and gripping handles from the outer ends -of the members for shifting the members relative to each other between the position of the plate-like body, and also designed to facilitate the manipulation of the device in its entirety.

In testimony whereof, I alfix my signature hereto.

JOHN SODERQUIST.
